Svetach [21]

Answer:

$2.40

Step-by-step explanation:

We know that the sales tax is 8% , we also know that we want to buy two t shirts that cost $15.00 each.

So first, look at what we are purchasing, two t-shirts costing 15.00 dollars each.

Since we are buying two, multiply $15 by 2,

==> $30.00 dollars

And since the sales tax is 8%, to find how much we will pay will mean to multiply the amount by the percent,

30 * 8%

==> $2.40 dollars

You will pay $2.40 dollars in tax
